Peer-to-Peer计算模型及其安全对策

Peer-to-Peer Computing Model and Security Countermeasure

介绍了P2P的定义,分析了当前P2P的五个模型的工作原理以及带来的影响,概括了P2P的特性,比较了P2P与传统Client/Server模型的区别。针对P2P技术带来的网络安全挑战,提出了解决P2P网络安全的对策,并着重对如何从信息安全的角度利用基于Agent的自适应技术监控Internet环境中P2P模式下的信息传播进行了探讨。

This article introduces the definition of P2P,analyzes the work principle of current five P2P models and the influence brought by them respectively, summarizes the characteristic of P2P and compares the P2P model and client/server model. P2P security countermeasure is discussed for the challenges brought by P2P.Specially, this article researches how to employ Agentbased adaptive technology to monitor and control the spread of information by P2P in Internet from the view of information security.
